Is there a way to practice 64bit on my VMWare?

You may recall that I am training myself to deploy using a VMWare virtual machine on my Windows Vista computer. I have successfully installed your 64bit VPS version on my actual server and wanted to know if there's a way to load this ( 64 bit ) upon a VMWare machine for practice. I would always delete the VMWare machine after practicing so I expect I would never be using it for more than 15 days.
If I can do this I'd be grateful to hear how?
Thank you,
David
